An indicator I like in QuoteTracker is a MACD using EMA parameters of 21.0 and 21.01 and a smoothing average of 17 and with a histogram display. Is there a MACD indicator available for WL that can accept floating point parameters?

No, not even in Community.Indicators, but you can always roll your own based on available examples:
WealthScript Programming Guide: Indicators > Indicators > How to: Create a MACD with Custom Periods
Community.Indicators source code - see MACDEx etc.
